Write a net ionic equation for the reaction that occurs when excess nitric acid (aq) and sodium sulfite (aq) are combined. Note: Sulfites follow the same solubility trends as sulfates.

Explanation:

Reactants  -

Nitric Acid

Sodium Sulfate

Products  -

Sulfuric Acid

Sodium Nitrate

The reaction is as follows -

Nitric Acid + Sodium Sulfate ⇒ Sodium Nitrate + Sulfuric Acid

⇒

To balance the above equation we need to add a coefficient of 2 in front of nitric acid on the right-hand- side and a coefficient of 2 in front of sodium nitrate on the left-hand-side.

∴ The balanced equation is as follows -

⇒

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
